Default Gas mileage and aftermarket exhausts

To all of you who have aftermarket exhausts,
Did you notice an increase in fuel milage (or decrease) after you installed the new muffler(and/or headers too) ?

After two fill ups, it seems I now get about 2 MPG more than what I had seen with the stock muffler.
